FAQ

Have questions? We have answers.

Everything you need to know about Modern Bio, GLP compounds, and getting started. You can always reach out to the team for more info at support@trymodernbio.com.

• How does Modern Bio actually work?

  You start by learning the science. Our free tools and guides walk you through dosing, mechanisms, and side-by-side compound comparisons, so you know exactly what you're working with before you buy. When you're ready, you choose your compound. Every vial ships at 99%+ purity with a batch-matched Certificate of Analysis, in discreet packaging, usually the same day. Our team stays with you after the order lands, on call 24/7 for reconstitution, dose math, and protocol questions. No prescriptions, no waiting rooms, no guesswork.

• What's the difference between brand name, compounded, and research GLP-1s?

  Ozempic®, Wegovy®, Mounjaro®, and Zepbound® are FDA-approved, brand-name medications made by Novo Nordisk and Eli Lilly and dispensed by prescription through a pharmacy. Compounded semaglutide and tirzepatide are different products, mixed to order by U.S. state-licensed compounding pharmacies; they are not FDA-approved and are not reviewed by the FDA for safety, efficacy, or quality.

  Research-grade compounds — semaglutide, tirzepatide, and retatrutide — supplied strictly for in vitro and laboratory research. They are not medications, are not intended for human use, and are not the same as, interchangeable with, or substitutes for any FDA-approved branded product.

• Are these peptides quality tested?

  Absolutely. Our analytical testing is conducted by Janoshik Analytical, BioRegen, or Freedom Diagnostics, independent third-party laboratories that verify the identity, purity, and composition of our research products. All products are guaranteed to test at 98% purity or higher. Each CoA includes purity analysis, peptide sequence confirmation, date of analysis, and an endotoxin report.

• What are typical delivery times?

  Delivery for our free shipping option typically takes 3–5 business days. We ship from right here in the USA to all US addresses. We also provide an option for next day shipping for an extra charge. Please allow 24 hours for processing.

  Every package comes with professional packaging and tracking updates via email.

• Are products stable during shipping?

  Our peptides are shipped in lyophilized (freeze-dried) form, which ensures stability during transit. This powder form is highly stable at room temperature and resistant to temperature fluctuations that occur during shipping.

  Research has shown no significant degradation or loss of purity when lyophilized peptides are exposed to room temperature during typical shipping timeframes. Each batch is verified for purity upon production, and our stability testing confirms maintenance of product integrity during standard shipping conditions.

• What payment methods do you accept?

  We accept credit and debit cards, Apple Pay, and Google Pay through a secure Square checkout. We also take cash pay and Zelle — both come with a discount for helping us avoid Square's processing fees.

  You'll get a confirmation email after you place your order. If you don't see it, check your spam or promotions folder, or contact support and we'll resend the link.

• What is the shelf life and expiration of peptides?

  Each lot lists a best-by/expiration on the vial label and COA. As general guidance, lyophilized peptides stored as directed are typically stable 12–24 months (often longer at –20 °C). Short shipping periods at ambient temperature are normal. Actual stability depends on sequence and storage conditions.

• Where can I learn more about the science and how to use peptides?

  Our Learn page is built for exactly that. You'll find interactive tools like the weight projection calculator, plain-language breakdowns of how each compound works, step-by-step reconstitution and dosing guides, and the research behind every molecule we carry. Explore it at your own pace, and contact the team any time if a question isn't covered.
